Abstract
A miniature sprinkler has a fixed, vertically extending nozzle having an inlet and an outlet, the inlet being for communication with a supply pipe. A flow diverter has an axially extending inlet in register with the outlet of the nozzle, the diverter including bearing apparatus for rotatably engaging the nozzle to rotatably mount the diverter at the top of the nozzle. The inlet in the diverter merges into at least one side outlet which extends generally horizontally and from which the water is emitted in the form of a jet, and a drive apparatus is coupled to the diverter in such a position that at least part of the flow from the diverter outlet impinges on the driver apparatus to cause the rotation of the diverter, the drive apparatus including a turbine slideably and rotatably mounted above the diverter for impingement thereon of the flow to cause rapid rotation of the turbine with a sliding motion. A cover member is coupled to the diverter and is arranged to be hit intermittently by the turbine for causing slower rotation of the diverter.
